What to buy in Iquitos / ¿Qué se compra en Iquitos?

To me, I don’t have any use for the trinkets that the natives were selling such as earrings or necklaces. Some of them were interesting such as the piranha necklace but I don’t know what to do with them. My recommendation is buy the bags – they’re made of natural items from the jungle and will last 3-5 years depending on amount of usage.
